I've been in a similar situation back in the 70's.
Remember those large very fast off shore speed boats?
Well a mate and I manage to get a berth on one of the smaller tall ships
around at that time and we went out to view the races.
Was a beautiful day with flat seas so the racers were going flat out.
At one point they were going away from us and the skipper decided
to reverse course and head back into Sydney and that we did.
What no one realized was that the race boats had already reached their
turn around point and were on there way BACK!
Yes on their way back going really fast [100 kph plus] and we were
right there in front of them.
My mate and I only had time to look at each other and they were past
just missing at stern and bow.
We agreed later that it had happened so fast that we had had no time to even
think about jumping overboard or anything else before they were past and gone.
With their size, speed and fuel on board it would have been a spectacular explosion!
Never heard anymore about it, so assume everybody just on with it!
